The torus command creates a three-dimensional plot data object, which when displayed is a torus centered at [x,y,z], whose meridian has radius r and distance from the center of a meridian to the center of the torus is R.

The plot data object produced by the torus command can be used in a PLOT3D data structure, or displayed using the plots:-display command.

Remaining arguments are interpreted as options, which are specified as equations of the form option = value. For more information, see plottools and plot3d/option.
